Risk from exposure to radiation and chemical agents at a coal-fired power plant

A programme including the investigation of simultaneous environmental and mutagenic effects of chemical and radioactive pollutants from a coal-fired power plant is in progress for several years. The coal-fired power plant has higher concentrations of natural uranium and descendents and a very high content of SO2. Investigations are under way first to define the path of chemical and radioactive pollutants in fly ash on site and off site. The second are the exposure studies of occupationally exposed workers. The WL inside the coal-fired power plant was measured taking into account the time spent by each worker at his work place. Previous bioassay investigations have demonstrated that some of the occupationally exposed workers has a high 210Pb level in urine corresponding chromosome aberrations. The occupancy time limit for the most exposed workers was determined
